What causes retinal hemorrhage?

Retinal hemorrhage is usually caused by vascular lesions in the eye. Common causes include the following: 1. Diabetic retinopathy: High blood sugar damages microvessels, leading to retinal bleeding. 2. Retinal vein occlusion: Formation of a blood clot within a vessel impedes blood flow and causes hemorrhage. 3. Age-related macular degeneration: With aging, blood vessels in the macular region become fragile and may bleed. 4. Retinal tear or detachment: Fluid from inside the eye seeps underneath the retina, sometimes accompanied by bleeding. 5. Vascular inflammation: Ocular inflammatory responses triggered by diseases such as tuberculosis or syphilis. 6. Eye trauma: Hemorrhage may occur following injury, such as blunt impact, or after surgery. 7. Hypertension: Long-term uncontrolled high blood pressure can affect the blood vessels of the retina. 8. Eye tumors: Certain ocular tumors may cause bleeding. Note: If retinal hemorrhage occurs, along with vision loss or dark shadows in the visual field, immediate medical attention is necessary.
